Investigators rule out battery in Boeing 787 problems

NORTH CHARLESTON, S.C. (WCIV) - Former Inspector General of the U.S. Department of Transportation Mary Schiavo explained the electrical system on which investigators have shifted their focus. They have ruled out the lithium ion battery in the Dreamliners as the cause of two plane issues.

"The system that controls the charging of the batteries, the system that senses when the battery has had enough, it'll shut it off. The system that senses when the battery is getting too hot," Schiavo said.

The lithium ion battery system used in the Dreamliner is new technology for planes.

"People are saying, 'Look FAA, why didn't you review this whole thing before it came to this?' So the government is in for a fair measure of criticism here too," she said.

Schiavo said jobs remain intact at Boeing South Carolina.

"Boeing can continue to legally assemble the planes and build them, knowing that once they get them built, they might have to go back and change something," she said.

Still, she said the Dreamliner will safely{}take off again.

"If we didn't come up with new systems on new planes, we wouldn't achieve what in the long run actually improves safety," she said.

The investigation could take weeks or months, Schiavo said. After that, she expected Boeing to have to get new certification for the electrical system. She said that could take months, as well.
